Answer:
0.7
Step-by-step explanation:
10y = 7x + 5
Divide both sides by 10.
y = 7x/10 + 5/10
y = 0.7x + 0.5
On a straight line of the form y = kx + m, k is the slope of the line.
In our line, y = 0.7x + 0.5, k is 0.7. Thus, the slope of our function is 0.7

At the beginning of the week, Joshua had $356 in his savings account. At the
end of the week he only had $123 in his savings account. Write and solve an
equation to find the amount of money that Joshua spent during the week.
equation: 356 - x = 123
The x can be changeable
the actual answer:
356 - 356 - x = 123 - 356
-1x/-1 = -233/-1
x =233
Find the slope of the line that passes through the points (2, -5) and (7, 1) Step 1: Choose (x1, y1) X1= ___ y1=___
Answer:
slope: 6/5

you do y2-y1 divided by x2-x1 so it will be 1-(-5) / 7-2 which is equal to 6/5
If EF=6 and EG=23 find the value of FG
Answer:
FG = 17
Step-by-step explanation:
EF=6 and EG=23
find the value of FG
6
E-------------F-----------------------------------G
|<-----------------------23---------------------->|
EF + FG = 23
6 + FG = 23
FG = 23 - 6
FG = 17
If y is directly proportional to x and y = 6 when x = 2, what is the proportion equation?
Answer:
y = 3x
Step-by-step explanation:
Direct proportion equation is
y = kx
6 = k*2
Divide each side by 2
6/2 = 2k/2
3 =k
The equation is y = 3x
Formula for direct proportion: y = kx
Solution:
6 = 2k
~Divide 2 to both sides
3 = k

find the value of x
Answer:
x = 68°
Step-by-step explanation:
∠ DCB = ∠ EDC = 27° ( alternate angles )
Thus ∠ ECB = 23° + 27° = 50°
The sum of the 3 angles in a triangle = 180°, thus
x = 180° - (62 + 50)° = 180° - 112° = 68°
Answer:
68°
Step-by-step explanation:
DE ║ BC
So, ∠DBC = ∠ADE = 62° (∵ Corresponding Angles are equal )
In triangle DEC ,
∠EDC+ ∠ECD = ∠AED (∵ Exterior Angle Sum Property of a triangle )
⇒ ∠AED = 23° + 27° = 50°
Now in triangle AED ,
∠EAD + ∠ADE + ∠AED = 180°
⇒ x° + 62° + 50° = 180°
⇒x° = 180° - 112° = 68°

During a heavy rainstorm, a city in Florida received
12 1/4 inches of rain in 25 1/2 hours. What is the approximate rainfall rate in inches per hour?
Answer: 0.48 in
Step-by-step explanation:
The problem asks for unit rate. To solve, let's convert the fractions to decimals.
[tex]12\frac{1}{4} =\frac{49}{4} =12.25[/tex]
[tex]25\frac{1}{2}=\frac{51}{2}=25.5[/tex]
Now that they are in decimals, we can set up a proportion.
[tex]\frac{12.25 in}{25.5 hrs} =\frac{x}{1 hr}[/tex] [cross multiply]
[tex]12.25=25.5x[/tex] [divide both sides by 25.5]
[tex]x=0.48[/tex]
Now, we know that there was approximately 0.48 in of rainfall per hour.

BD = DC because angles ADC and ADB are right angles.
Thus, [tex]4x-5=2x+7[/tex]
Add 5 to both sides:
[tex]4x-5+5=2x+7+5[/tex]
[tex]4x=2x+12[/tex]
Subtract 2x from both sides:
[tex]4x-2x=2x+12-2x[/tex]
[tex]2x=12[/tex]
Divide both sides by 2:
[tex]\frac{2x}{2}=\frac{12}{2}[/tex]
[tex]x=6[/tex]
DC [tex]=4x-5[/tex]
[tex]=4(6)-5[/tex]

For a given recipe, 10 cups of flour are mixed with 20 cups of sugar. How many cups of flour should be used if 4 cups of sugar are used? Assuming a constant ratio, fill out the table of equivalent ratios until you have found the value of x.
Answer:
2
Step-by-step explanation:
If 20 cups are used on the first recipe then 4 are used on the second, the way to find the answer is to divide 20 by 4. 20 divided by 4 will get 5. Now we have to divide the 10 cups of flour by 5 which in the end will get 2.

Given the function f(x)=2x-7. What is x when f(x)=17?
Answer:
x = 12
Step-by-step explanation:
Step 1: Define
f(x) = 2x - 7
f(x) = 17
Step 2: Substitute
17 = 2x - 7
Step 3: Solve for x
Add 7 on both sides: 24 = 2x
Divide both sides by 2: 12 = x
Step 4: Check
f(12) = 2(12) - 7
f(12) = 24 - 7
f(12) = 17
Answer:
f(17)=2(17)-7
=34-7

factorise 9(a+b)^2 + (a+b) -8
Answer:
[tex](9a+9b-8)(a+b+1)[/tex]
Step-by-step explanation:
[tex]9(a+b)^2 + (a+b)-8[/tex]
Expand [tex](a+b)^2[/tex]
[tex]9(a^2+2ab+b^2)+a+b-8[/tex]
[tex]9a^2+18ab+9b^2+a+b-8[/tex]
Now it is time to think.
Once
[tex]9a^2=9a \cdot a[/tex]
[tex]9b^2=9b \cdot b[/tex]
[tex]18ab=9ab+9ab[/tex]
[tex]-8=-8 \cdot 1[/tex]
We can get something in the format

The boiling point of three components A, B and C of petroleum are 120○C, 70○C, 250○C respectively. If a mixture of these three is fractionally distilled, which of these will be obtained at the bottom of the distillation column?
Answer:
Mustaali Chill Bro
Component C, with a boiling point of 250°C, will be obtained at the bottom of the distillation column.
The component with the highest boiling point will be obtained at the bottom of the distillation column.
In this case, component C has the highest boiling point at 250°C, followed by component A at 120°C, and component B at 70°C. Therefore, during fractional distillation, component C will be obtained at the bottom of the distillation column.
